The LV8729 is an ultra-quiet in-line driver module developed to meet the needs of the market. It is simpler to use and is the choice for a quiet environment for printers.feature of product:1. In the 64 subdivision or 128 subdivision, you can have a better ultra-quiet effect;2. Working voltage: 6V-36V, the recommended voltage is 12V;3. The maximum current is 1.5A, the default is 0.8A;4. Subdivision: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128;5. 4-layer PCB board with the back side of the chip facing up, plus heat sink for better heat dissipation.

The A4988 module is a DMOS microstepping driver with converter and overcurrent protection, which can operate a bipolar stepper motor in full, half, 1/4, 1/8 and 1/16 step modes, with output-driven performance up to 35 V and ± 2A. The A4988 also includes a fixed off-time current regulator that operates in slow or mixed-decay modes.
